Numerical Simulation of Methane Flux Measurements Using Lidar

摘要

The authors propose a lidar system for remotely measuring methane flux in the atmospheric boundary layer. The concentration is measured using differential absorption lidar, the vertical velocity is measured using aerosol-correlation lidar, and the flux estimates are obtained using the eddy-correlation technique. Numerical simulations using a Monte Carlo approach show measurement uncertainties of about 50% in the methane flux for reasonable system parameters.
